Unravelling the “Black Box”: Treatment-Staff Perceptions of Hermon Prison’s Drug-Rehabilitation Program

This current qualitative study analyzed treatment-staff perceptions of the advantages and weaknesses of Israeli’s primary prison-based drug rehabilitation program, as implemented in Hermon Prison in Israel. Semi-structured interviews were conducted with 12 social workers and recovery mentors who worked as therapists in Hermon Prison during the research period. The analysis showed that the main advantages described were that the program was varied (included psychotherapy, education, vocational training, and work) and required a 1-year stay in a therapeutic community setting, with intensive exposure to eclectic psychotherapy methods and was delivered in a prison that is organizationally and architecturally designed to serve treatment goals. The primary weaknesses that the therapists perceived were shortages of treatment staff (staff turnover was high), individual psychological therapy and of follow-up treatment in the community. The research suggests that reducing these deficiencies may improve the program’s effectiveness, and it offers an initial theoretical model for creating an effective drug rehabilitation program

Use of DNA testing in police investigative work for increasing offender identification, arrest, conviction and case clearance

The use of DNA testing as part of police investigative work has increased substantially since its emergence in the 1980s. The objective of this review has been to synthesize the existing evidence on the effectiveness of DNA testing as part of routine police investigative practices compared to other more traditional forms of investigation. We have identified five studies that clearly addressed the effectiveness of DNA testing as part of a criminal investigation to improve criminal justice system outcomes. The evidence suggests that DNA testing has positive value when used to investigate a broad range of crime types. There are caveats. Other than a methodologically sound evaluation in five U.S. jurisdictions, the evidence of the utility of DNA testing for serious violent crimes is based on studies with clear methodological weaknesses

Determinants of penetrance and variable expressivity in monogenic metabolic conditions across 77,184 exomes

Hundreds of thousands of genetic variants have been reported to cause severe monogenic diseases, but the probability that a variant carrier develops the disease (termed penetrance) is unknown for virtually all of them. Additionally, the clinical utility of common polygenetic variation remains uncertain. Using exome sequencing from 77,184 adult individuals (38,618 multi-ancestral individuals from a type 2 diabetes case-control study and 38,566 participants from the UK Biobank, for whom genotype array data were also available), we apply clinical standard-of-care gene variant curation for eight monogenic metabolic conditions. Rare variants causing monogenic diabetes and dyslipidemias display effect sizes significantly larger than the top 1% of the corresponding polygenic scores. Nevertheless, penetrance estimates for monogenic variant carriers average 60% or lower for most conditions. We assess epidemiologic and genetic factors contributing to risk prediction in monogenic variant carriers, demonstrating that inclusion of polygenic variation significantly improves biomarker estimation for two monogenic dyslipidemias

A novel RFC1 repeat motif (ACAGG) in two Asia-Pacific CANVAS families

Cerebellar ataxia, neuropathy and vestibular areflexia syndrome (CANVAS) is a progressive late-onset, neurological disease. Recently, a pentanucleotide expansion in intron 2 of RFC1 was identified as the genetic cause of CANVAS. We screened an Asian-Pacific cohort for CANVAS and identified a novel RFC1 repeat expansion motif, (ACAGG)exp, in three affected individuals. This motif was associated with additional clinical features including fasciculations and elevated serum creatine kinase. These features have not previously been described in individuals with genetically-confirmed CANVAS. Haplotype analysis showed our patients shared the same core haplotype as previously published, supporting the possibility of a single origin of the RFC1 disease allele. We analysed data from >26 000 genetically diverse individuals in gnomAD to show enrichment of (ACAGG) in non-European populations

An Information Theory Approach to Hypothesis Testing in Criminological Research

Background: This research demonstrates how the Akaike information criterion (AIC) can be an alternative to null hypothesis significance testing in selecting best fitting models. It presents an example to illustrate how AIC can be used in this way. Methods: Using data from Milwaukee, Wisconsin, we test models of place-based predictor variables on street robbery and commercial robbery. We build models to balance explanatory power and parsimony. Measures include the presence of different kinds of businesses, together with selected age groups and social disadvantage. Results: Models including place-based measures of land use emerged as the best models among the set of tested models. These were superior to models that included measures of age and socioeconomic status. The best models for commercial and street robbery include three measures of ordinary businesses, liquor stores, and spatial lag. Conclusions: Models based on information theory offer a useful alternative to significance testing when a strong theoretical framework guides the selection of model sets. Theoretically relevant ‘ordinary businesses’ have a greater influence on robbery than socioeconomic variables and most measures of discretionary businesses

Researching the use of force: The background to the international project

This article provides the background to an international project on use of force by the police that was carried out in eight countries. Force is often considered to be the defining characteristic of policing and much research has been conducted on the determinants, prevalence and control of the use of force, particularly in the United States. However, little work has looked at police officers’ own views on the use of force, in particular the way in which they justify it. Using a hypothetical encounter developed for this project, researchers in each country conducted focus groups with police officers in which they were encouraged to talk about the use of force. The results show interesting similarities and differences across countries and demonstrate the value of using this kind of research focus and methodology

Portraying the nature of corruption: Using an explorative case-study design

What is the nature of corruption in Western democracies? To answer this research question, the authors study 10 Dutch corruption cases in depth, looking at confidential criminal files. The cases allow them to sketch a general profile of a corruption case. The authors offer nine propositions to portray the nature of corruption. They conclude that corruption usually takes place within enduring relationships, that the process of becoming corrupt can be characterized as a slippery slope, and that important motives for corruption, aside from material gain, include friendship or love, status, and the desire to impress others. The explorative multiple case study methodology helps to expand our understanding of the way in which officials become corrupt. © 2008 The American Society for Public Administration
